what the hell is this muti cylinder missfire bullshit code i have been trying to figure out for 3 years. it will only pop on if i go over a hundered a few times. it starts flashing everytime i go over 100mph but once i do it a couple times it will stay on saying p0300 muti cylinder misfire. i have already replaced iacv,tps,plugs,fuel filter, air filter, air temp sensor. the only thing i havent done was replace all the coils.

Have you had a dealer do diagnostic?

I had s problem w/ a p305(?) code. Turned out to be a bad alternater creating radio frequency that fooled the PCM into giving false code.

Good luck, let us knowis u find soloution.

Camshaft position sensor (CMP) Low fuel: less than 1/8 tank Stuck open EGR valve Blocked EGR passages. The car needs to be data logged, if you know how send me the file.

how do i data log it?? wouldnt a cmp and egr throw a code??? I do get a weird feed back out of my radio like a wining sound that gets more high pitch as you give it gas. idk if its the aftermarket deck thats in it or something else.
